Bitcoin’s active supply is declining as coins that have remained unmoved for years come to be considered part of inactive supply, amid lower daily new issuance following the 2024 halving.

As bitcoin consolidates its role as a savings and treasury asset in Latin America, some coins fall out of active circulation due to loss of access, prolonged inactivity, or succession issues. The phenomenon adds pressure on the management and protection of these assets.

According to data from Glassnode and Fidelity Digital Assets, more than 566 BTC enter the ancient supply every day, made up of coins that have been inactive for more than a decade. The figure exceeds the 450 BTC that miners produce daily following the 2024 halving.

Lost access reduces the available supply.

The situation highlights a problem associated with holding bitcoin: some funds can become permanently inaccessible when passwords are lost, devices are discarded, or there is no mechanism to transfer the assets after their owner’s death.

Effective circulating supply is estimated at between 15.8 and 17.5 million coins, below the 20 million established by the protocol. Recovery options depend on the source of the loss: some custody errors can be reversed, while funds in burn wallets are unrecoverable. The 1.1 million BTC attributed to Satoshi Nakamoto have remained unmoved for more than a decade.

Succession planning gains relevance in the region.

In Latin America, bitcoin is used both as a savings vehicle for individuals and as a treasury asset for companies. In this context, a lack of inheritance planning and proper custody practices represents a risk for investors entering the ecosystem without fully understanding the implications of self-custody.

Luis Ayala, General Manager for Latin America at BitGo: “The most interesting story in crypto in Latin America is not the price, but the utility. Bitcoin is becoming everyday infrastructure for payments, savings and remittances. Scaling that safely means solving the one problem that self-custody cannot solve at population scale: a lost key is money lost forever. Qualified custody removes that single point of failure, so that growth rests on trust, not individual heroics”.

Custody practices seek to prevent permanent losses.

Specifically, avoiding the loss of bitcoin requires not relying on a single device or password, keeping backups in at least two secure locations, and documenting a succession plan that allows a trusted person or lawyer to manage access in the event of death or incapacity.

It is also recommended to avoid storing access information on internet-connected devices or unencrypted cloud services, periodically check that hardware wallets remain compatible and functional, and replace them before they fail due to obsolescence.

For significant amounts, the material also suggests considering qualified custody services rather than relying exclusively on individual self-custody.

Bitcoin is thus taking a place as a long-term asset in institutional and personal portfolios in the region, raising the need to also address its protection and estate continuity. Qualified custody services manage private keys, operational continuity, and estate transition.
